One of the worst strains I ever grew
Ignore the ignorant posts and the cheezie laugh emoji!
Just because GG#4 was not an intentional cross. Makes little difference to it's quality as to the ORIGINAL.
I got it way early on and it grew very well. Other then being a Mg hog AND liking N..
As far as ANY viral issue goes?
MOSAIC viral's ARE NOT an issue in cannabis! PERIOD! Any "HEMP" mosaic is named for "Sunn Hemp" mosaic virus, and THAT effects BEANS!
BTW? Sunn Hemp? IS A BEAN!
It is likely that if you ACTUALLY have a viral issue. It'll be a HOPS virus!
There aren't many either!
I STILL run clone after clone after clone of the original GG#4 I got all those years back too.
While over the years it has done and ENVIRONMENTAL shift (to better match the dominate pheno traits to the environment it's growing in)
It has NEVER had any issues.
NOW THEN.
Your issue is CLEARLY to much P, to early in bloom!
Unfortunately, many nutrient makers outright LIE about the use of "bloom boosters"... It's marketing, not truth!
Their products tend to drop the N to much and at the same time, they raise the P to much!
I have never had a "Hermie" issue with it either. Grow it right and you don't have those problems....
For the most part. You ain't getting the real deal GG#4 if your buying seeds off the net. There is only 1 place to get them and yer better off getting the clone from them over the beans.... They are the REAL guys...
Peace out
